I need help please! Peter creates a square pyramid

model for History class. The

base of the pyramid has an

area of 20 square inches. Each

triangle has an area of 10

square inches. If Peter wants to

cover the entire pyramid with

gold paper, how much paper

will he need?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer is 33
